SCH I535 w/Straight Talk no calling or outgoing texts - Verizon Samsung Galaxy S III

I got my ST SIM activated yesterday and LTE connected without having to make any APN changes.
I can receive incoming text messages. Incoming calls go straight to voicemail, and I receive a notification for them but cannot retrieve.
Outgoing calls /messages result in 'no mobile network' error, including dialpad codes.
Have had six different sessions with Straight Talk, whose solution, depending upon the CSR, has been to change the APN, restart phone/pull sim/battery, factory reset, wait for activation, etc.
At one point, Verizon Wireless briefly appeared as the carrier but LTE stopped working.
Any suggestions? I have done all of the above, along with installing several different ROMS, restoring earlier backups, etc.
I have searched and found a lot of posts regarding issues with data, but can't find anything relating to my particular issue.
I am currently on CM13 Nightlies. The phone is not under contract and I have used it with other BYOP carriers with no issues.
Thanks!

I was helping someone else out with that recently. I found that both on CM12 and CM13 it doesn't give you the option to change the APN settings.

I am actually able to change the APN settings by selecting the APN, editing it, and saving it from the menu pull-down. In a few of the ROMS I tried, I needed to put in the updated APN of TRACFONE.VZWENTP. (I laugh every time I type it.. VZ went P heh)
Anyway, in some ROMS it works with the assigned APN and in others I have to put in the updated one for LTE to work. The APN is for internet and MMS, both of which are working at the moment. I need to figure out how to get calls and outbound SMS working.

Yes, I just got the Straight Talk SIM and network code and activated it a few days ago. I looked for the apps but could only find one for account management and auto-APN settings.
I was using a prepaid T-Mobile sim in this phone prior, and had to use an older modem to get data (only got edge since it's GSM on a CDMA phone) working. I am currently installing a newer modem to see if that will help.

Yeah that's the one I saw. I installed it just in case, but it only changes the APN settings, which I have already tried. Thanks though!

Not a problem. Sorry I couldn't be of more help

[Q] HTC One E8 bought from Etotalk APN issues (AT&T)

So I bought the HTC Once E8 from Etotalk, which came with all the Chinese apps removed and the Google Play store added. I went to the ATT store to get a nano sim, and calls and texts work just fine. My issue is with the data connection. I have done a lot of google fu, and have tried the same settings that people are using for UK M8's but am still having issues. From my understanding the bands are supported, so It should just be a configuration issue.
Would anybody be able to shed some light on this for me? This is my first overseas phone, and I have only had experience with vanilla Android installs to date.
Also, the first thing I did was install the software update from HTC, which probably wasn't the smartest move. I don't see how this would affect APN settings though....
Let me know if any other info is needed, thanks in advance for any help!!

You probably lost the etotalk modrom while updating, but that shouldn't be a big deal. Though it may have overwritten the predefined APN settings?
Did you manualy check your APN settings under settings --> mobile data --> sim1 --> access point names?

Yeah that's what I think happened, is that I lost the modrom. I wouldnt think that would affect the APN though, isn't that supposed to be unique to each country, or something of the sort? I will send Etotalk a message and ask them if there's a chance that could be it anyways.
I have indeed tried keying it in manually, trying every combination from default, to the one I got from the ATT rep, to the ones I have found online from different forums.
Fixed
I tried using the legacy cingular APN. Apparently my grandfathered unlimited data plan was on these old codes, ie. 3G only...
Thanks anyways.

Latest VZW OTA/Firmware update 4.4.3 removes 'New APN' setting.

I noticed that under Network settings for Global or GSM, the New APN feature to manually add an APN for different sim is gone. Looks like it's an auto detect feature now. I travel overseas for business alot and use pre-paid SIM cards. Not all prepaid sim cards have the data APN coded. I just found out on my trip here to Taiwan and couldn't get data on my phone because the option for adding the APN is no longer available. I tried multiple settings, different ROM's and no good. Only when I downgraded my firmware did the option come back. Glad I'm rooted, it sux, but had to downgrade and reflash back to the old 4.4.2 firmware/rUU and run custom ROM. Until this is addressed by verizon, there will be no way to manually add an APN.

Update: Figured the APN issue thing out
Thanks to member DOTTAT for giving me the direction I needed to get the APN assignment issue resolved. I just needed to do things differently for getting the APN to load up. Basically had to to to the 'Network Preferences' section to add the network my SIM cards are registered on. This is a long list to scroll through. After I selected the network, there is multiple options to add the network type (GSM,UMTS,LTE, etc.) Had to enable three different versions then reboot the phone. After, there were two APN's that automatically populated and I was able to edit. Thanks again to DOTTAT for the direction. :laugh::good:

I apologize but I did not see the steps to get the apn settings access. I've got the HTC One M7 for Verizon on 4.4.3 and can not change apn settings. What would the steps be? Thank you so much for any and all help.

I figured I'd bump this thread rather than start a new one... It seems I and many other Verizon M8 users have encountered the same problem:
I get no list of network APNs under "Network Preferences." There are zero entries, even though a message pops up to say the list is full.
I tried manually entering the MCC/MNC numbers for my carrier abroad (Claro Brazil) but this doesn't resolve the problem. I am stuck with only voice but no mobile data service.
Has anyone found a solution to this? Verizon tech support of course insists "just pop in the SIM and it should work automatically" as does the Brazilian carrier.
Does anybody know where in the phone the APN settings are stored, to edit them manually?

APN Issue on US Cellular

I have an unlocked US Cellular Galaxy S6 and I use my Straight Talk sim card (running off AT&T towers) and calls and texts work but there's no option anywhere in settings to enter apn settings. I bypassed this using an app but I would like to know a fix and not just a work around. I'm VERY familiar with Androids and I've never encountered this issue and searching hasn't led me to any answers.
Anyone? I also keep getting a + symbol with incoming calls and its annoying
Anything? Lol

There's a thread over at teamuscellular.com. it involves getting into the service menu. I used a USC S6 on TMO for a while. Also maybe a csc edit to show the default apns, and you'll just edit it and it'll stick. It's been a while...I'm just trying to point you in the right direction.

Lineage OS 7.1.1: Unable to send SMS messages

Hello all,
I flashed my girlfriend's Sprint S5 with Lineage OS recently without a hitch, all services working perfectly. We ended up traveling, so she went to Sprint to set up a temporary international roaming plan. Everything was completely as expected abroad. When we got back, her phone would not send SMS messages.
We tried the usual airplane mode and such, and to no avail. Assuming something was wrong with the network configuration from travelling, we reset network settings. Didn't work. I then decided to just do a full wipe and re-flash of Lineage OS. Still doesn't work. I then resorted to going back to the stock TouchWiz ROM from Sprint. At that point, under the stock ROM, SMS were sending. Out of curiosity, we flashed back Lineage OS, and SMS will again not send. We noticed that if the SIM card is removed, SMS will send, but the phone would not be able to access 4G LTE. We also confirmed with Sprint that there are no restrictions on the account.
What could be causing this to occur only on custom Roms? Do we need to do a PRL update? If so, how does that work on stock Android?
Thanks in advance!
S5 sprint No outbound sms
I've had this problem for weeks....So far the only solution is using Google voice app....
I'm using LOS 7.1.1 20170207 kltespr nightly, LTE SMS can only receive, sending doesn't work. Only 3G SMS works.
Things I noticed:
Settings -> About Phone -> Status -> IMEI Information. When on 3G, all information is displayed here, when on LTE, only IMEI and IMEI SV is displayed, there's no PRL/MIN/MEID/ICCID anywhere, not even disabled or greyed out, just hidden completely.
ICCID also shows DUMMY_NV_ICC_SERIAL instead of the actual ICCID.
Same experience for me, I've been trying to find a workaround for over a month with no success. Alternative text messaging apps seem to work, but I don't trust 3rd parties with my SMS.
Unable to send SMS
Mike.
Which third party SMS app are you getting to work? Besides Google voice I have had no luck with any third party app?
I'm having the same issue. I'm on Resurrection ROM which is based on Lineage. Since update I can't send SMS at all other than via Google Voice. I can receive SMS and I can send/receive MMS.
I did find that if I change to 3g only for my network settings, I can send SMS. But then of course I don't get LTE data speeds for everything else. So the issue for me at least is tied specifically to LTE. Wondering if there is an APN or other setting I can change that would fix this but so far no luck finding anything.
Bug reported since 01/28
https://jira.lineageos.org/browse/BUGBASH-37
I've run into the same problem or similar. If I set my preferred network type to GLOBAL then I can send and receive SMS/MMS messages but I'm forced to either Roaming LTE or 3G. It's often stuck in 3G after a drive for any distance. If I force it to LTE, then SMS/MMS stops working and I can't place or receive calls either but the network will show up as LTE and Sprint.
To get there from Settings Home -> More (under Wireless and Networks) -> Cellular networks -> Preferred network type -> Choose Global.
Sometimes I can force it back to LTE but roaming if I switch temporarily to LTE then once it connects switch back to Global. Occasionally I have to put it in airplane mode to get the radios to reset and connect but some combo of switching network type and ending up in global and switching into and back from airplane will do the trick.
YMMV of course.
one way I fix it temporarily is to:
cell networks - carrier settings, let it crash
go in again and let it find your carrier
once connected, make a phone call at least to get it ringing
I can then make sms mms.
it's a rediculous work around but it works for me every time
SMS Sending Problem with Lineage 14.1 (31.07.2017)
Heyy
I'm not able to send sms from SIM 1 but can send sms from SIM 2 in Lenovo A6020a46 (2GB) on Lineage 14.1 (31.07.2017).
The same SIM is working good in another roms and Calling + Internet are working properly.
After dialing *#*#4636#*#* in Phone Information - SMSC Refresh then it appeared "Phone no.", 456 and I pressed Update.
But there was no process for saving or updating. Then I reentered in Phone Information but SMSC Shows blank.
What to do??? anybody help in this matter will be immensely appreciated.

I made this file using Odin with the steps from here. I flashed the file, set the connection to LTE aand it worked. https://forum.xda-developers.com/showpost.php?p=71582847&postcount=5908
To fix this issue with having LTE signal and sending SMS at the same time you have to open EnginneringMode app (or *#*#3646663#*#*) and check 'Sms over Sgs support' in Misc Feature Config tab.

If that code doesn't work for you, try to find an app called Engineering Mode MTK. Unfortunately I cannot attach any screenshots yet (I got less than 10 posts).
fix
there is an option in network settings (enhanced 4G LTE mode for comunications etc) i disabled that option and messaging works fine now. before unchecking this option i could only send sms only with phone on 3g mode, now it works fine. i think this option is for hd voice calls via 4g lte.
I see this is an old problem and I´m having the same problem. I can receive SMS, but I can´t send.
But to add to that, I couldn´t connect at all with my previous carrier and changed carrier after which I can use data, call and send SMS. I still can´t receive SMS.

Stock Rom (rooted) APN settings unable to be edited or added

Hi guys,
I've been running the stock rom (6.0.1) with RingPlus for about 4 months now, and just got word that they were discontinuing service. I canceled my service with them and have moved to Tello, which many of the users on RingPlus were saying was a painless switch. I've received my Tello phone number, and activation/provisioning instructions, which I've followed several times. I'm able to make and receive phone calls, but don't have 3g or LTE data.
From my experiences with Nexus devices and AT&T MVNO's my gut says it's an APN setting, but when I browse to the APN list the whole list is grayed out and unchecked, the add button is also grayed out.
Does anyone know how to open this up?
This issue is solved. I used a hidden menu (##3282#) to view my APN settings and they were being pulled from Tello. Later in the day my phone randomly did a prl update (several dozen had been done since posting this thread) and after that update everything worked. My best guess is that the line wasn't fully activated.
Hi Thunderbolt,
My phone is rooted and after putting in the MSL and dig down I have the same issue as APN Type and many other options are greyed out. I'm with Sprint. Looks like you haven't done anything and it automatically became available. What's Tello? Do I need to install any otger app to get the access? Thanks.
I'm on Stock TouchWiz Marshmallow on my S5 Sport G860P and my APN settings aren't greyed out, but they don't save when I add the proper APN for my FreedomPop SIM I received yesterday.
Is there a way to unlock this phone for free? I bought it on Ebay used and it has a clean ESN. I'm not the original owner so I don't have to Sprint account number and I may not be able to get it because it was purchased from a reseller.

What does it mean to use a hidden menu? And what is Tello? I am having this problem as well and would love to fix it. My issue is ultimately about not sending and receiving MMS consistently. But having the prn menu grayed out isn't helping my efforts to fix it.
Thanks!

Open dialer Punch in ##3282# this brings up the hidden menu for a lot of things.. Choose edit, and if it ask for you MSL enter it, then go to apn settings and you can add one, it should not be greyed out.
